Making Jams and Jellies

Grape Jam
without added pectin

  • 2 quarts stemmed Concord grapes
  • 6 cups sugar

Yield: About 6 half-pint jars

Please read Using Boiling Water Canners before beginning. If this is your first time canning, it is recommended that you read Principles of Home Canning.

Procedure:

Sterilize canning jars. Separate pulp from skins of grapes. If desired, chop skins in a food blender or chopper. Cook skins gently 15 to 20 minutes, adding only enough water to prevent sticking (about ½ cup). Cook pulp without water until soft; press through a sieve or food mill to remove seeds. Combine pulp, skins and sugar. Bring to jellying point, about 10 minutes. As mixture thickens, stir frequently to prevent sticking. Fill hot jam into hot jars, leaving ¼ inch headspace. Wipe rims of jars with a dampened clean paper towel; adjust two-piece metal canning lids. Process in a Boiling Water Canner.
